5. MBF ACTUATOR ANALYSIS
Use your fingers to move the MBF Actuator.
Does the MBF Actuator function correctly, without binding or sticking?
Yes No
Go to Step 6. Replace the MBF Sensor Actuator.
6. BOTTOM PLATE ASSEMBLY ANALYSIS
When the paper cassette is empty, does the MBF Actuator fit in the cut–out at the bottom
of the Plate Assembly?
When there is paper in the cassette, does the MBF Actuator touch the top sheet of paper?
Yes No
Go to Step 7. Replace the MBF Sensor Assembly.
7. MBF SENSOR ANALYSIS
Use Diagnostic Tool test DG02 to check the MBF Sensor function.
Does the MBF Sensor function correctly and increment the DG02 number each time you
actuate it?
Yes No
Replace the MCU PWB. Go to Section 6.3.9
MBF Sensor Failure.
8. NO–PAPER ACTUATOR ANALYSIS
Use Diagnostic Tool test DG02 to check the No–Paper Actuator function.
Does the No–Paper Actuator function correctly and increment the DG02 number each
time you actuate it?
Yes No
Go to Step 9. Replace the No–Paper Actuator.
9. NO–PAPER SENSOR ANALYSIS
Use Diagnostic Tool test DG02 to check the No–Paper Sensor function.
Does the No–Paper Sensor function correctly and increment the DG02 number each time
you actuate it?
Yes No
Replace the MCU PWB. Go to Section 6.3.10
No–Paper Sensor Failure.
